    Hey hey brother, thanks for you step by step guide for bios downgrade, I followed each and every step and reached to bios 1.06 but I used Method 1 for stopping and after next reboot my system came back to 1.09 BIOS version. I really need your help to stop reinstalling 1.09.
    If you can share your any social app, so I can discuss with you.

    Hello bro, did you uninstall the firmware before restarting or after restarting?  Because you have to do that before restarting by going here:-

    If you did not uninstall this before restarting then try to downgrading it again and then uninstall it.
    And the other thing to keep in mind is to not install this optional update as it is a bios update and you should keep them unselected:-

    And if the issue still remains unresolved then you have to follow the 2 method of downgrading as that will definitely work. And if you face any trouble installing windows then you can follow this guide https://community.acer.com/en/discussion/628141/how-to-install-windows-10-pro-for-free-on-acer-predator-helios-300#latest .

    And if you still face any issues then let me know.

    Hey man, I’m trying to downgrade my bios to 1.06, but I noticed Flags is already set to 0 so it won’t let me downgrade. Is there a workaround to this because I’m throttling like crazy?
